Recent Black screen of death/random restart
* ASUS PRIME X470-PRO AM4 * AMD Ryzen 7 2700X + Wraith Prism Cooler * 2x8GB G.SKILL TridentZ RGB DDR4 3000 * GIGABYTE RTX 2070 OC White 8GB 3X Windforce * PowerSpec 750 Watt 80 Plus Bronze PSU * Samsung 1TB EVO 2.5 SATA3 SSD * 64-bit OS, x64 based processor
**Issue:**
3 times within the past few days my computer crashed with a black screen. 2 times during games(Valorant) and once while I was AFK. I came back from eating to see all the same symptoms. All fans/RGB still running. No response and no signs of auto restarting or anything. Even holding down the power button did not shut my computer off. I had to flip the switch on the power supply.
Just today, while I was playing Vermintide 2, my computer randomly restarted. That's when I decided to make this post.
**History:**
When I first built my computer I used the D.O.C.P profile to set it to 3000 mhz 16-18-18-38 1.35V, no other changes. That caused my computer to blue screen(Stop code: irql\_not\_less\_or\_equal) so I changed it back to the default 2133 mhz. That fixed the blue screen issue. I didn't do any CPU tinkering. Everything else was set to their default/auto settings. I left it like this(8 or so months) without any issues.
**Recent changes:**
May 25, 2020: I was itching to get my RAM up to 3000 mhz, since well... I bought it for that reason and it should be more than capable. I did a little research and saw some posts about incrementing the RAM's voltage up .05 at a time until things are stable. So with D.O.C.P disabled, I manually changed everything to match the D.O.C.P settings(3000, 16-18-18-38) except changing the voltage from 1.35 to 1.4 volts.
A few days later, I wanted to boost up my CPU a bit from 3.7 to 4.0. I did so by upping the CPU core ratio in the BIOS to 40. All the other settings/power settings I left on auto/default. Precision Overclock boost all set to auto. I never monitored my computer's performance/temps until I started doing these recent changes. I noticed that my CPU jumps well over 4000 mhz during games(I've seen it as high as around 4800). I assumed this was the Precision Overclock boost. Even then I checked with HWMonitor and the max temps never passed 70 C. Although, I can't confirm if there was ever a spike before the black screen crashes since they were random.
June 3, 2020: One more odd thing that happened was after I opened up my computer and connected the Wraith Prism Cooler RGB to the motherboard. I finished and tried to turn on my computer. Lights up, fans move, but black screen and no USB power... I eventually power down, unplug and take out the CMOS battery for about an hour. Turn it on and voila, it works. I repeat the process, but put the battery back in. Everything seems good.
A couple of weeks go by without any issues, but within the last few days my computer has black screened 3 times and randomly restarted once.
I have now set everything in my BIOS back to what it was during it's stable state.(Although, Precision Boost Overdrive is all set to auto. I think this is how it was by default. Not 100% sure on this).
Even if things stay stable like this, I don't like the fact that I can't overclock to these not too extreme levels. I could be doing it wrong, like changing the CPU core ratio while leaving it's voltage/power settings on auto? Or maybe I was overclocking the RAM correctly? Obviously i'm just an amateur so any help/tips are welcome.
Maybe I need a new CMOS battery? Maybe a new PSU or Motherboard? I know hardware issues are tough to diagnose so any help is appreciated.
